No. 274,427 S Claims. (El. 239 3tl7) This invention relates to paint sprayers and more particularly to handy apparatus for selectively spraying any one of a plurality of sprayable uids.

More particularly, the invention has to do with readily portable apparatus employing a container having Freon or other suitable gas under pressure in combination with a plurality of sprayable fluid containers, the contents of any one of whichmay be selectively aspirated and atomized in a spray jet, for use in furniture renishing and other similar operations. The apparatus comprises an economical support for a duid pressure container, and the sprayable fluid containers, connecting tubes, a cornmon pressure control valve, and novel valve and aspirating means for at will selecting the particular sprayable uid desired.

The above and other novel features of the invention will appear more fully hereinafter from the following detailed description when taken in conjunction with the accompanying drawings. It is expressely understood that j the drawings are employed for purposes of illustration only andare not designed as a definition of the limits of the invention, reference being had for this purpose to the appended claims.

FIGURE 10 is a fragmentary sectional View taken on the line Ill-lil of FIGURE 8, and

FIGURE l1 is a side elevational view of a further modicaticn.

In FIGURE 1 there is shown a pressure fluid container 2t? containing a gas such as Freon and one or more containers 22, 24 and 26, or jars, three being shown, containing a selection of stains, lacquer, paint or the like, which are likely to be of use on a particular job. The jars are held in position on standard screw thread caps 28, 3i? and 32. The caps are fastened to a support plate 35, in clover leaf formation, by screws 36, and above the `support plate is a sheet metal shelf bracket 38 to which is detachably atiixed the container 20. Such container has a bottom annular rib 21 adapted to be seated within the upwardly projecting inbent fingers d@ and 42, formed integral with the bracket 33. The bracket 38, and plate have overlapping anges 44 and 46 along their back edges,l and if desired the plate 35 and shelf bracket 33 may be formed all of one piece folded .over lat 5d, or the plate and shelf and their ilanges may be soldered or otherwise secured together. A thumbscrew 52, threaded through the overlappingr portions of the flanges de and 46 is adapted to engage the backside of the container Ztl United States Patent lOy ICC

immediately above the annular rib 2l. It will thus be seen that the container 2d is readily replaceable, as often as its supply of pressure medium becomes expended. Also it will appear that the containers 22, 2d and 26 are likewise readily removed and replaced or relilled, as desired. While screw threaded engagement with the caps 21S, 3@ and 32 have been indicated as at 33, any bayonet type engagement for quick attachment anddetachment may be employed as will be understood by those skilled inv the art.

The container 2d is provided at its upper end with a threaded nippe 6l within which is disposed a valve 6d, for controlling the release of gas from the container. Threaded on the nipple is a cap 63, having a flexible diaphragm 62 in its upper end, from which depends a valve depressing plunger de, which is actuated by the thumb lever 6d pivoted to the cap as at 65. The cap makes sealed engagement with the nipple, and is readily removed from the container for removal or replacement thereof.

Projecting laterally from the cap at divergent angles, are nipples 7G, 72 and 74, such nipples being threaded into the caps in leak tight manner. Lock nuts such as 76 may be employed behind which is a sealing washer 7S. Each of the nipples has a small bore Sti extending there- Y through which may be of a diameter of the order of 25 thousandths of an inch and such bore is enlarged at its loutlet end as at 82. Threaded over the end of the nipple is a shroud or sleeve dd, and a nut 86, and lock washer S3 serve to tix the sleeve upon `the nipple. The end of the sleeve is cut on a slant as at 9i?, and the .projecting lower portion or lip thereof is threaded as at92 to receive an aspirating nipple 9d having a bore @6. The upper end of the nipple M is conical, as at 9d, and the lower end is unthreaded as at Idil. The nipple may be screwthreadedly elevated or lowered within the sleeve to align the aspirating end 162 with the jet iiow of pressure gas from the outlet end 32 of the bore titl. A finger sleeve Idd is disposed upon the nipple 94, and locked in place between clamping nuts Ille and 193 to facilitate rotation of the nipple and to establish correct aspirating adjustment of the aspirating end lili in relation to the aspirating gas stream.

Each of the nipples 7d, '72, and '74 are provided with identical sleeves S4. The aspirating nipple 94 of each sleeve 8d is provided with a plastic tube connection such as lid, I IZ and 11d extending to the respective jars 22, 2d and 26, the tubes Il@ and lid projecting directly through the jar caps 28 and 32 to extend into the jars in a concentric fashion, while the tube M2 extends between the platform 35 and shelf 38 and enters the jar 24 through an aperture 3l in cap Btl. A Wire bracket 113, aiiixed to the underside of cap 30 depends into jar 24 and loops around the tube IIZ to hold the same concentric within the jar. It will be understood that the'tubes are of a length to substantially reach the bottom of the jars, and are held concentric to assure that the tubes will in no way interfere with the quickly removal of or replacement of the jars.

In order to select the jar from which liquid is to be aspirated, each of the nipples 70, 72 and 74 and their respective sleeves Sd are provided with a valve 119, so that by closing off any two of the nipples 70, 72 and 74, and opening the valve of the other, the contents of a selected jar may be aspirated and sprayed. As shown in FIGURE 5 the sleeve and nipple is provided with a threaded recess 12% having a flat bottom that extends to Within a short distance of the bore of the nipple. The flat annular bottoni i122 has a central conical annulus 323, as formed by a drill point, the conical annulus providing a surface of generation at about 60 degrees from the axis of the threaded recess. The conical annulus deiines an aperture 12d into the bore Sil of a diameter, a little larger than metiers :J the diameter of the bore. A circular disk of rubber 130 of a thickness of about one half the diameter of the disk is disposed Vin the bottom of the recess 120. A thumb screw 140, having a knurled head M2, and standard end i configuration, may be brought to bear upon the rubber disk, and cause a central portion 132 to elasticaily distend'into the bore Sil to seal the same. Upon releasing the pressure of the thumb screw upon the disk, the disk tends to elastically return to its disk like conguration, the distended portion reducing in extent, as the screw pressure `is released, to permit the ilow of gas from the reservoir container 2t). Any ldesired adjustment of the thumb screw 169 may be made to nicely control the jet stream velocity.

It will be seen from the foregoing that there is provided a relatively inexpensive holding bracket for securing a container .of uid pressure, such as Freon in association with one or lmore liquid containers with means for selectively aspirating and spraying any one of the liquids within the liquid containers. Furthermore, the apparatus is handy to use, and subject to easy and quick replacement of the various containers, as replenishment or variations in the liquids'to be sprayed becomes desirable. In order to replace the fluid pressure container, release of the screw 52, and unthreading of the container from cap '63 is all that is required. As soon as a fresh container is threaded into the cap and secured to the bracket 36, operation may continue. The placement of jars, or relling of any one of the jars is also easily eiected, by the mere unscrewing of the particular jar from plate supported cap. Furthermore by rotation of the jet 94, by manipulation of the thumb and nger Sleeve 104 the jet 162 is moved up or down in reference to the jet from any one of the nipples, such as 72, and ready regulation of the power of such jet is had by the manipulation ofthe thumb screw `119, to regulate the discharge. The lower end of the nipple 92 is-left smooth as at 160 so that the nipple is readily rotated relative to the tube 110, without causing the tube to move axially, and at the same time forms a sealed con-y nection to the tube.

While three liquid containers are illustrated, it will of course appear that any number of such containers may be accommodated in accordance with the number of jar caps and aspirating nozzles provided. ln practice a single such jar may be all that is desired.

In FIGURES 8 to 10 there is shown a modified form of the invention wherein the jar containers are located along side of the pressure uid container. As shown, the pressure container 2t? supports a yoke 150, having a circular aperture 152 to t over the cylindrical portion 154 of the pressure container, above the shoulder 156. Such.

yoke may be made of hardwood, plastic or the like. The yoke is provided with a plate 15S secured thereto by small bolts 16d. Aihxed to the plate are threel screw cap jar tops 162, 164 and 166 as by bolts 168. The yoke is provided with a pair of thumb screws 170 to grip the container. The pressure container cap 63 is provided with three nipples 172 extending radially therefrom at 45 angles. 84, each having avalve 119, and aspirating nipple 941-, as shown inFIGURE 4. Each aspirating nipple is provided with a thumb and iinger sleeve 174 clamped between nuts 175, to permit threaded adjustment of the nipple in respect to the gas stream from thepressure container 20. The lower ends of the nipples extend through apertures 17 3 in their respective jar covers, and have an Unthreaded portion 166 at the lower end, over which a straight section of suction tube 181 is fitted of suilicient length to reach approximately to the bottom of the jar 183. A small washer 1.8i) is threaded on the nipple above the tube and the clearance `between the sleeve 174 and washer is suicient to permit the nipple and its tube yto be screwed up or down freely to adjust the aspirating ciect as desired.

As before, the operator opens one of the valves 119, as desired and operates the spray through manipulation of Each of the nipples are provided with sleeves Y y from the jar tops.

the valve lever 6e. In FGURE 11g-the yoke is eliminated, and a small plastic vial 190, with'a screwcap 192 is provided with a nipple 1% screw threaded into the sleeve V84. The nipple'is clamped in the cap head by nuts 198,.and the lower end of the'nipple is'unthreaded, and fitted with'a suction tube 200:

In this modification, `adjustment of the aspirating effect is had by rotation of the vial, .cap and nipple as a unit. While a single vial, and nipple 196 are shown, it will be understood that thethree nipple. arrangement of FIG- URES 8 to l0 may be used without the yoke and cap assembly, by using three vials'directly hung from the sleeves S4 by their respective nipples'196. Suitable air vents in the caps are' provided.

ln FGURES 9-11 inclusive, to replace a pressure container 2t?, itis merely necessary to loosen the thumbscrews 17h, and unscrew the container 2t? .from the cap 63.' Vari'- lous jars of different paints, enamels, or rfinishing materials may be readily substituted by unscrewing the jars It will be seen that the apparatus is handy in that up to three diierent finishing materials are readily available, and lapplied by a single replaceable pressure container. Although reference to paints, enamel and finishing liquids have been referred to it, it Will at once appear that the apparatus is economical and can readily be employed for spraying any liquid. The invention avoids the uneconomical mixing of a liquid to .be sprayed with the pressure liquid in a single container, and at thek same time provides for the handy application of any one of a multiple ot sprayable liquids. In each modification the kaspirating sleeve S4 providesa handy economical valve, andV opportunity for precision adjustment of the Y aspirating spray.

While several applications of the invention have been illustrated and described, itis to be understood that the invention is not limited thereto. As various changes in the construction and arrangement maybe made without departing from the spirit of the invention, as will be apparent to those skilled in the art, reference will be had to the appended claims for a denition of the limits ofthe invention.
